Where it goes
Is Cobblemon: Glitchdex required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Cobblemon: Glitchdex 1.2 need?
1.2. Change the file and its required mods may change too.
Install Cobblemon first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

Q&A
Can I use this mod in my modpack?
- Absolutely! Credit is appreciated. Can I use this addon in my public server?
- You may under the condition that none of the content in this mod is locked behind a paywall of any kind. This includes lootboxes that can be purchased with real money, even if the player can earn them for free.
Where are they?? 😭
- All Glitchmon can spawn in the Nether at Y-levels greater than 110. I'd advise clearing out a large area to give them room to spawn.
- MissingNo. and 'M can spawn at beaches, although extremely rarely.
Where is my GOAT [insert Glitchmon here]?
- There's a lot of Glitchmon out there, and I can't realistically add every single one. I will only add glitches that are not hybrids of other Pokemon, and are not clones of *other* Glitchmon.
- Glitchmon clones are combined together into one fakemon.
- 'M is the exception to this, as it is too iconic.
Credits
- All modeling, spritework, and sound design was done by me.

- Sounds Resource and Freesound for providing sounds used to create the cries.
